y Application led October 2,1917, Serial No. 194,338. Renewed September27, 191g. Serial No. 255,292.

To all whom z't may concern.'

Be it known that I, Josnrr-i Honvnrrr, a subject of the Emperor ofAustria, and residing at Detroit, in the county of Wayne and State ofMichigan, have invented a new and Improved Lubricator, of which thefollowing is a specification.

. This invention relates to automatic lubricators of the same'generaltype as those shown in my pending application, Serial Number 154,098,and to selfclosing filling devices for such lub-ricators and othercontainers requiring illingdevices that may be firmly held in closedposition.

ThisV invention consists in the details of construction illustratedinthe accompanying drawing and particularly pointed out in the claims.

In the drawings, Figures 1 and 2 are central longitudinal sections ofone embodiment of the present invention showing the filling device intwo positions. Figs. 3 and 4 yare similar sections of another embodimentof the invention and Fig. 5 is an elevation thereof.k Fig. 6 is asection of the filling device and plan of the guide plate of thestructure shown in Fig. 3. Fig. 7 is a section .of the filling plungerand plan of the upper part of the body shown in Fig. 2.

Similar reference characters refer to like parts throughout the severalviews.

The lubricant receptacle, the cap therefor, theguide plate therein, themovable plunger and the cap or button atthe upper end.

of the plunger are all preferably stamped out `of sheet metal, `brass orsteel being the metals usually employed. In Fig. 1, the lubricantreceptacle or body 1 of the lubricator is formed with a threaded neck 2by means of which it is attached to the part to be lubricated and inwhich neck a short dischar e tube 3 is securely held. The cap 4 may beformed with a proper inwardly extending guide and sealing flange 5provided with a notch 6 to permit the rib or spline 7 on the plunger 8to slide freely therein.

The guide plate 9 has a circumferential cylindrical ange 10, and aspring 12 between this guide plate and the flange 13 at the lower end ofthe plunger 8 normally holds the plunger down. A cap or button 14 issecured to the upper end of the plunger and receives a washer 15 thatserves as a packing to prevent leakage between the button and the flange5. The plunger has a ller opening 16 and the passage through the tube 3is normally closed by means of the ball valve 17. When the plunger is inits lowermost position, the' projections 18 formed from the metal of theplunger prevent the ball from jumping too high from I.

its seat. f

When the lubricator is to be lled, the plunger 8 is lifted until the ribor spline 7 is above the flange 5 when the plunger is turned, as in Fig.1, the lower end of the rib 7 resting on the flange 5 which constitutesal The 'lubricator' circumferential shoulder. may now be filled throughthe h'ole 1G. The

Dlungerlis of sufficient length to still incloseV the ball 17 when theplunger is at its highest position and prevent from rolling oif the I'end of the part 3.

When the. plunger is released and forced -to the position shown in Fig.2, the ball 17 is. permitted to roll on the upper end of the tube 3 toopen the passage therein, but be'- cause the interior diameter of the,plunger 8 is little' greater than the diameter of the ball,`

Instead of forming the rib at the upperY end of the plunger and thenotch Yin the flange 5 at the top of the capvof the body, the rib 19 maybe formed near or below the middle of the plunger and the guide plate 9may be formed with a notch 20 to receive the rib. In this case, theguide plate constitutes the circumferential shoulder upon Vwhich the endof the rib rests when the plunger is in its elevated position to uncoverthe opening 16.

I claim 1. The combination of hollow interior and exterior members, oneof said members having an internal guide plate and the other an externalVflange, a spring betweenl the guide plate and flange, one of themembers having a longitudinal rib and the other member a notch in whichthe rib is slidable Y ing an internal guide plate and the interiormember having a circumferential flange, a v

spring between said plate and ange, said interior member having alongitudinal rib and the exterior memberbeing formed with a notch inwhich the rib is slidable and from which the rib may be moved to permitthe interior member to be turned.

3. In a lubricat'or, the combination Vof an outer stationary memberprovided with an inwardly extending rim anda guide plate, an innermovable member provided with a filler opening,a longitudinal rib and acircumferential flange, and a coil spring between the plate and tlange,said outer member having a guide notch to receive said rib and ont ofwhich the rib isV moved when the filler opening is exposed.

4. In a lubricator, the combination of an outer stationary memberprovided with an inwardlyT extending rim and a guide plate, a hollowinner movable member provided with a filler opening, a longitudinal riband a circumferential flange, and a coil spring between the plate andiange, said plate being formed with a guide notch tov receive said riband out of which the rib is moved when the iiller opening is exposed,said rib riding upon the plate when. the iimer member is turned. Y

5. In a lubricator, tlie combination of holvlow interior and exteriormembers, the interior member having a filler opening, means to move therinterior member downwardly,

said interior member having a longitudinal rib adapted to slide withinthe notch in the guide and to vrest upon the guide when moved out of itandvafter which the inte? rior member is turned; Y ,f

8. In a lubricator, the combination of hollow interior and exteriormembers, the interior member having a lille'r opening, means to move theinterior member downwardly,

said exterior member being provided with a notched guide for theinterior member and said interior member having a longitudinal ribadapted to slide within the notch in the guide and to rest uponk theguidel when moved out of it and after which the 111-- terior ,member isturned, said exterior membei being formed with a discharge opening,

a ball valve normally closing said opening and limited in its lateralmovements by the interior member. t

9. In a lubricator, the combination of hollow interior andexteriormembers, the in terior member having a filler opening, meansV to movethe interior member downwardly, said exterior member being providedwith` a notched guide for the interior member and said interior member`having a longitudinal rib adapted to slide within the notch in theyguide and to rest upon the` guide whenV moved out of it `and after whichthe interior member is turned, said exterior member being formed with adischarge opening,- a ball,

valve normally closing said opening and limited in its lateral movementsby the interior member, said interior member having inwardly extendingprojections to limit the upward movement of the ball; Y
